CONCRETE BLOOK AND WALL.

Specification of Letters Patent.

Application filed October 11, 1909.

Patented Jan. 2, 1912. Serial No. 522,067.

To all whom it may concern:

Be it known that I, LYMAN G. LEASE, citizen of the United States,residing at Howland, in the county of Trumbull and State of Ohio, haveinvented certain new and useful Ii'nprovements in Concrete Blocks andlValls, of which the following is a speoification.

, This invention has for its object an improved construction of wall andbuilding blocks or tiles therefor, the said blocks being formed on oneor more faces with a groove or depression designed to produceventilating openings through the walls. And the invention consists incertain constructions, arrangements and combinations of the parts that Ishall hereinafter fully describe and claim For a full understanding ofthe invention, reference is to be had to the following description andaccompanying drawings in which:

Figure l is. a sectional perspective view of a portion of a wallconstructed with my improved building blocks, illustrating anarrangement whereby longitudinally and substantially continuous airpassages are formed in the wall. Fig. 2 is a perspective view of oneform of block employed; Fig. 3 is. a similar view of a modified form ofblock; and, Fig. 4 is an end view of one arrangement of the blockshereinafter specifically referred to.

Corresponding and like parts are referred to in the followingdescription and indicated .in all the views of the accompanying drawingsby the same reference characters.

Referring to the drawing, the numeral 1 designates one form orembodiment of my improved building block or tile, which may be made ofany desired substance such as concrete, or vitrified materials asdesired. The blocks 1 are formed in one Wall with :an inwardly curvedlongitudinally extending portion, as indicated at 2, producing on theexterior of the block a longitudinally extending groove or depression 3,which is preferably a little deeper than the wall or side of the block,as shown. By producing this groove, as shown in the drawing, it will henoted that the wall of the block or tile is not weakened, but issubstantially of uniform thickness. It is to be understood that thesegrooves may be formed in one or more of the walls of the block or tile,and may be formed either along the median line of the wall of the blockor at either side of such line. The grooves 3 are preferablysemicircular in cross section. Obviously the blocks may be arranged inthe building wall with the grooves of the two adjoining blocks meetingso as to produce a cylindrical ventilating opening as illustrated inFig. 4. Or, the grooved wall of one block may be arranged contiguous tothe straight or plane walls of the two adjacent blocks, so as to rectionof the arrows in Fig. 1.

From the foregoing description in connection with the accompanyingdrawings, it

is obvious that a wall built of blocks constructed in accordance with myinvention may be provided with ventilating openings extendinglongitudinally and continuously in any desired course by laying .theblocks end to' end, and that any one or more of the courses may beprovided with transversely extending ventilating openings by placing anyone or more of the blocks transversely of the wall, that is, with itsgroove extending from front to rear.

Obviously my invention is not limited to a hollow block or tile, nor toa hollow block or tile as illustrated in Fig. 1. For instance, asillustrated in Fig. 3, a modified form of block designated 1, may beused. This block maybe provided with a web 4 and with the grooves 3 inopposite Walls at opposite sides of the Web.

Having thus described the invention, What is claimed as new is:

A wall constructe of a plurality of courses of hollow blocks, the blocksbeing open from end to end and those of each course being laid end toend whereby to afford an uninterrupted air passage extending the en tirelength of each course, each of the blocks being formed in one wall witha depression extending the entire length thereof, that portion of thewall of each block opposite the depression being plane, the blocks ofeach course being arranged alternately with the depressed Wall of eachblock presented in the same direction as the plane wall of tha adjacentblocks of the same course, the i In testimony Where-0f afiix mysignature depresslon of each block reglstermg m presence of two'WLtHSSSQS. thrmw'hout a partion of it lPiwth Witb *lw ZMAN .LE-AF. lhs.dapressmn of a related block 0f an ad acent v b J L 1 course whereby toestabllsh commumcatlon Wl'tnessesz at intervals between the air passagesof the G120.
